ogcode: Skill for Claude Code

.agents/skills/firebase-firestore/SKILL.md

firebase-firestore is a skill for Claude Code, Codex from prasenjeet-symon/ogcode. It costs 138 tokens per session (1,093 once invoked), scanned A, original, AGPL-3.0.

A guide for using Cloud Firestore, Firebase's hosted NoSQL database for storing and querying app data. It covers data models, security rules, indexes, and SDK integration for web, Python, iOS, Android, and Flutter.

In plain words
What is it for?
Use it to create databases, design stored data, add indexes, write queries, configure security rules, and connect supported apps through SDKs.
Why use it?
It removes guesswork from setting up Firestore and making app data access secure and efficient.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is prasenjeet-symon/ogcode's own configuration. It tells Claude Code and Codex how to work on ogcode itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ogcode configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

firebase-firestore scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 16d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
